The web is made by extrusion from a die outlet which defines the configuration of the grooves and ribs 3, 4, and impressing the indentations in the web at the exit of the die, by means of a roller bearing ribs and grooves matching those of the web, and projections from its ribs for impressing the indentations. The impressing may cause elongation of the web. The grooves 3 and 4 may be rectangular, or saw-toothed, Fig. 4 (not shown), or may be of different configuration across the width of the web to ensure a constant thickness upon thermoforming. The indentations may be hemispherical, trapezoidal, octagonal, or cubic. The surface 2 may be rendered planar, by simultaneously extruding a film thereon, or a pair of webs may be simultaneously extruded with surfaces 2 facing each other and laminated to a film providing barrier resistance to ultraviolet radiation for manufacturing long life packages. The shaping profile of the die and roller may be obtained by engraving, or electro erosion, and the roller may comprise a coating of antiadherent material.

The second switching circuit means is operated to one of the on and off conditions by the control means to charge the capacitor 34, through the first direct current source to operate the first switching circuit means to one of the on and off conditions to energize the ignition coil, the second switching circuit means being further operated to the other one of the on and off conditions by the control means to discharge the capacitor through the second direct current source to operate the first switching circuit means to the other one of the on and off conditions to collapse the field in the ignition coil to cause an ignition spark. Resistive means 5 1 is coupled from the first switching circuit means to the second switching circuit means to hold the second switching circuit means in the other one of the on and off conditions thereof with the first switching circuit means in the other one of the on and off conditions thereof. The ratio of current passing through the first direct current source to the current passing through the second direct current source at engine RPM above cranking speed is such that the capacitor charges to an amount less than the total capacity thereof prior to the discharge of the same thereby providing energizing of the ignition coil for a constant percentage of the total period between ignition sparks, whereas at engine cranking speed the frequency of operation of the second switching circuit means permits the capacitor to completely charge through the first direct current source to provide a constant off time of the current through the ignition coil at such cranking speed.
